Parrot Command-Line Options
Since Parrot is both an assembler and a
bytecode interpreter, it has options to control both behaviors. Some
options may have changed by the time you read this, especially
options related to debugging and optimization. The document
imcc/docs/running.pod should have the latest
details. Or just run parrot —help.
General Usage
parrot [options]file[arguments]
The file is either an
.imc (.pir) or
.pasm source file or a Parrot bytecode file.
Parrot creates an Array object to hold the
command-line arguments and stores it in
P5 on program start.
Assembler Options
-
-a, --pasm Assume PASM input on
stdin. When Parrot runs a source file with a.pasmextension, it parses the file as pure PASM code. This switch turns on PASM parsing (instead of the default PIR parsing) when a source file is read fromstdin.-
-c,--pbc Assume PBC file on
stdin. When Parrot runs a bytecode file with a.pbcextension, it immediately executes the file. This option tells Parrot to immediately execute a bytecode file piped in onstdin.-
-d,--debug [hexbits] Turn on debugging output. The
-dswitch takes an optional argument, which is a hex value of debug bits. (The individual bits are shown in Table 11-3.) Whenhexbitsisn’t specified, the default debugging level is 0001. Ifhexbitsis separated from the-dswitch by whitespace, it has to start with a number.Table 11-3. Debug bits
